Abstract

The invention discloses a high-voltage electric field low-temperature plasma cold sterilization device, and belongs to the technical field of frequency converter power supply circuits. According to the high-voltage electric field low-temperature plasma cold sterilization device, a frequency converter, a first-stage inductor, an electric voltage regulator, an alternating-current contactor and a solid-state relay are arranged on the front portion in a shell, a transformer is arranged on the rear portion of the shell, the transformer with a large size is arranged on the inner side of the shell, and the frequency converter, the first-stage inductor, the electric voltage regulator, a second-stage inductor, the alternating current contactor and the solid-state relay which are small in size are located on the outer side of the shell, so that mounting and dismounting are convenient, and the working conditions of all structures can be observed conveniently. The frequency converter is externallyconnected with the first-stage inductor, so that the output voltage is controllable, harmonic components in modulation waves are suppressed, the frequency spectrum is expanded, and the harmonic current entering a voltage regulation module is stable.

Description

technical field

[0001] The invention relates to the technical field of frequency converter power circuits, and more specifically relates to a high-voltage electric field low-temperature plasma cold sterilization device. Background technique

[0002] Plasma is the fourth state of matter. It consists of an ionized conductive gas, which includes six typical particles, namely electrons, positive ions, negative ions, atoms or molecules in an excited state, atoms or molecules in a ground state, and photons.

[0003] The ions, electrons, excited atoms, molecules and free radicals enriched in the low-temperature plasma space are all active particles, which are easy to react with the material surface. Therefore, it is widely used in sterilization, surface modification, thin film deposition, etching processing, device cleaning and other fields.

[0004] High-voltage electric field low-temperature plasma cold sterilization is a new type of food cold sterilization technology in the wo...
